Are you wondering how stone coated metal roofing tiles work and protect your house?
1) Technical Structure
Up-down anti finger-print coatings + up-down alu-zinc coatings + galvalume steel base. This ensures every piece is as strong as steel to protect your house without corrosion problems.
2) High-Quality Materials
Sintered Stone Chips: Sintering is the process of forming a solid mass of material by heat or pressure. This technology guarantees beyond 20 years on color retention. Unlike pre-painted chips that fade in 2-3 years, sintered stone offers permanent color stability.
Galvalume Steel: Composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. Alu-zinc steel lasts 6-9 times longer than ordinary galvanized steel by using an aluminum barrier to protect the steel core.
Acrylic Glue: The durability of the adhesive is key. High-grade acrylic technology is used to ensure stone chips do not flake off, providing resistance to UV degradation from the sun.
📦 Packing & Loading
Advanced production lines ensure an output of 800,000+ pieces per month. Orders are typically finished within 10-15 days.
❓ Frequently Asked Questions
How long is the warranty for these roofing tiles?
Our stone coated metal roofing tiles offer a 30-50 year limited warranty, with at least 20 years of guarantee against significant color fading.
What is the difference between sintered and painted stone chips?
Sintered stone chips are formed through high-heat processing, ensuring the color is bonded within the stone. Painted chips only have a surface coating that typically fades within 2-3 years.
What is the Minimum Order Quantity (MOQ)?
The MOQ is 500 pieces for stone coated metal roofing tiles and 200 square meters for asphalt shingles.
Are these roofing tiles heavy for the house structure?
No, they are lightweight. Despite being made of steel, they are designed to reduce the structural load on the building while providing superior protection compared to traditional clay or concrete tiles.
Can I get a sample before placing a full order?
Yes, free samples are available upon request. You only need to cover the freight cost.
How well do they resist wind and heat?
These tiles are designed for extreme conditions, offering excellent wind resistance, heat insulation, and 100% waterproofing.
